Firebase推送承诺永远不会解决

Question

I am trying to save an object from my React Native App. Please look at the below code snippet.

  const { currentUser } = firebase.auth();

  firebase.database().ref(`/users/${currentUser.uid}/employees`)
    .push({ name, phone, shift })
    .then(() => {
      console.log('Save to Firebase was successful');
    })
    .catch((error) => {
    console.log(error);
  });

But in the Firebase console, I don't see anything. I am surprised that the then and catch don't even get called. What am I missing? The console does not show any error.

My Firebase DB Rules:

Here's my Firebase realtime DB view:

Question- I am pushing to /users/${currentUser.uid}/employees path, do I need to manually create 'users' node?

Answer 1

In Firebase push() function genrates a unique key for each new child, and set() or update() functions insert or update data in node.

Try this:

  firebase.database().ref(`/users/${currentUser.uid}/employees`)
    .push()
    .set({ name, phone, shift })
    .then(() => {
      console.log('Save to Firebase was successful');
    })
    .catch((error) => {
    console.log(error);
  });

Or this:

 let niceKey =  firebase.database().ref(`/users/${currentUser.uid}/employees`).push()

niceKey.set({ name, phone, shift })
    .then(() => {
      console.log('Save to Firebase was successful');
    })
    .catch((error) => {
    console.log(error);
  });

Answer 2

Don't use push to save data to Firebase, instead use set or update . Here's how it works:-

firebase.database().ref(`/users/${currentUser.uid}/employees`).set({
    name: name,
    phone: phone,
    shift : shift
});
